First of all, I come from Iowa, the unofficial Hog state and commercial operations are not necessarily cleaner, they stink more and are not all cruel and inhumane. Secondly, I have friends here who have a pig and they haven't said anything about special permitting or having issues with the state of Tennessee. I'm confused now. Are there special permits I need for pigs? I'm not talking 100, just 4 or 5.
They don't live in squalor, they only get muddy to cool off and I will rotationally graze them.
I have had large pigs and mini pigs both and none of my pigs have ever been allowed to live in squalor! I rotate them and clean their pens when needed. No permits needed that I know of. My pigs stay cleaner than my dogs by the way!
